May people help via giving sprites? For example, Pokémon Iberia, Titan and Opalo, all of them Spanish games, have a lot of rippeable sprites. And also Pokémon Reloaded, which i was able to obtain the battle sprites too. Here, see the sprites for yourself https://drive.google.com/file/d/1OmdeccN2yQial6R7CqrAurGSMx0YNg6T/view?usp=sharing
True link, wasn't able to attach the zip due to size...
Just credit F3R and the Pokémon Reloaded Team if you want to use them... i do not own these files.
